Dennis,
I say INIT but I am really referring to the 'FORMAT' parameter of
CPFMTXA. Below is an example of an EXEC to format cylinder zero with the
z/VM Label. The INPUT file 'INPLVD1' has the RDEV and LABEL.
Of course you can do the same by executing CPFMTXA interactively and
specifying to parameters as prompted:
/**** OR USE *****/
trace o
makebuf;
'EXECIO * DISKR INPLVD1 FILE A (STEM' RECORD. 'FINIS'
do i = 1 to record.0
rdev = word(record.i, 1)
label = word(record.i,2)
queue 'format'
queue rdev
queue '0-0'
/* queue '0-END' */
queue label
queue 'YES'
queue 'PERM 0-0'
/* queue 'PERM 0-END' */
/* queue 'PAGE 1-END' */
queue 'END'
cpfmtxa;
End;
dropbuf;
INPLVD1 file:
6C6A B34V80
6C6B B34V81
6C6C B34V82

How do you init, with CPFMTXA?
Thanks, cause I still waste all that time.

Hi Marcy,
I use to format the whole volume under CPFMTXA or ICKDSF on z/OS and
then turn around only to have Linux format them again a real waste of
time.
So now I just init cylinder zero with a z/VM Label for doc purposes and
it works fine.
Thank You,

When we *had* zLinux POC guests, we formatted them under CMS using the
LXFMT utility, see:
http://www.sinenomine.net/products/vm/lxfmt
Once formatted with LXFMT, the disk was accessible from Linux without
dasdfmt. But your particular filesystem needs may require something
more
extravagant.

Re: ICKDSF format of new DASD
Hi Marcy
Based on our experience, we have no problem formatting just the first
five
cyl (0-5) before we attached them as linux dasd device mdisks. In turn,
they will format them using their own linux utilities.

What is the current recommendation for new DASD purchases and ICKDSF
CPVOL
FORMAT for disk to be used for Linux.
We've been formatting the whole thing. Once upon a time there was a
DASD
driver bug that this helped avoid, but I'm sure that has been fixed
before.
